Description

Technical Field

[0001] This utility model relates to the field of support components, specifically to a folding side support leg and a mining vehicle. Background Technology

[0002] In the field of construction machinery, vehicle structures with telescopic booms are often used to achieve large-scale operations. When the telescopic boom is fully extended to the side and in operation, the huge overturning moment generated by the boom, cargo and its own weight will all act on the front frame, which can easily cause the whole vehicle to tilt to the side or even overturn (for example, when the boom of a mine chute strut conveyor is fully extended to the side, the front frame will tilt). Therefore, side outriggers need to be installed on the side of the vehicle body for support. However, the traditional side support leg structure has obvious drawbacks: when the vehicle is not in operation (transfer or driving), the side support leg needs to be folded back. However, even when folded, the structure itself will still protrude to the side of the vehicle body, occupying additional space on the side of the vehicle. This makes it inconvenient for the vehicle to pass through or move in narrow spaces (such as alleys, tunnels, factories, etc.), and it is very easy to be scratched or collided, which limits the application scenarios and work efficiency of the vehicle. Utility Model Content

[0003] The purpose of this utility model is to provide a folding side outrigger and a mining vehicle, which solves the problem of obvious drawbacks of the existing traditional side outrigger structure.

[0004] The present invention achieves the above-mentioned objective through the following technical solution: a folding side support leg, installed on a mining vehicle, comprising: a steering support assembly, wherein a folding support leg is hinged to the steering support assembly, and the folding support leg rotates around the steering support assembly and is in a folded position stored in the mining vehicle or extended out of the working position of the mining vehicle.

[0005] Preferably, the folding support leg includes a first arm hinged to the steering support assembly and a folding support leg hinged to the first arm, wherein the steering support assembly is provided with a drive member for driving the first arm to rotate and change its angle.

[0006] Preferably, the folding support leg includes a second support arm hinged to a first support arm and a support leg hinged to the second support arm. The second support arm is provided with a first fixing hole and a second fixing hole. The support leg is provided with a second pin. The second pin is used to insert into the first fixing hole when the support leg is unfolded, and the second pin is also used to insert into the second fixing hole when the support leg is folded.

[0007] Preferably, the support leg includes a kit, a movable leg slidably disposed within the kit, a positioning hole disposed on the movable leg, and a positioning pin disposed on the kit for insertion into the positioning hole.

[0008] Preferably, the support leg is hinged with a support foot.

[0009] Preferably, the steering support assembly includes a mounting base, a hinge seat hinged to one side of the mounting base, and a limiting plate provided on the other side of the mounting base. The limiting plate is provided with two pin holes, and the hinge seat is provided with a first pin for insertion into the pin holes. The first arm is hinged to the hinge seat, and the two ends of the drive member are respectively hinged to the first arm and the hinge seat.

[0010] Preferably, a first support rod is hinged to the hinge seat, and a second support rod for hinged to the first support rod is hinged to the first support rod. The first support rod is provided with a guide groove, and the hinge joint between the first support rod and the second support rod is slidably disposed in the guide groove.

[0011] Preferably, a mining vehicle includes: a vehicle body and a folding side support leg as described above, mounted on the vehicle body.

[0012] The beneficial effects of this utility model are as follows: by rotating the first support arm from the working position to the folding position through the steering support assembly, the orientation of the folding side support leg is changed, so that the folding side support leg is rotated from the lateral working position to the folding position which is roughly parallel to the longitudinal beam of the vehicle body. This avoids the folding side support leg occupying the space on the side of the vehicle when installed on the vehicle, significantly reduces the overall lateral profile size of the vehicle, greatly improves the vehicle's passability and maneuverability in narrow alleys, tunnels and other restricted spaces, and solves the contradiction between operational stability and spatial passability.

[0015] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0016] Example 1 Please see Figure 1 and Figure 2 A folding side outrigger includes: a steering support assembly, on which a folding support leg is connected; the folding side outrigger is installed on a mining vehicle for use.

[0017] It should be noted that the folding support leg rotates on the steering support assembly and can be stored in the folding position of the mining vehicle or extended to the working position of the mining vehicle.

[0018] In this embodiment, as a further optimization, please refer to... Figure 1 and Figure 2 The folding support leg includes a first support arm 5 and a folding support arm; the first support arm 5 is hinged to the steering support assembly, and a drive component 6 (such as a hydraulic cylinder) is hinged between the steering support assembly and the first support arm 5 to drive the first support arm 5 to rotate and change its angle; the steering support assembly is used to change the direction of the first support arm 5, so that the first support arm 5 is in a folded position or a working position. When the first support arm 5 is in the folded position, it is perpendicular to the steering support assembly (because the steering support assembly is installed on the side of the vehicle, the first support arm 5, when rotated to the folded position, will move into the interior of the vehicle and be parallel to the longitudinal beam of the vehicle), and when it is in the working position, it is on the same straight line as the steering support assembly (at this time, the first support arm 5 is perpendicular to the longitudinal beam of the vehicle); the folding support leg is hinged to the first support arm 5.

[0019] It should be noted that the steering support assembly can consist of a mounting base 1, a hinge base 2, and a hydraulic cylinder. The hinge base 2 is hinged to the mounting base 1, and the two ends of the hydraulic cylinder are respectively hinged to the mounting base 1 and the hinge base 2. The hydraulic cylinder extends and retracts, driving the hinge base 2 to rotate on the mounting base 1, which is used to steer the first support arm 5. The steering support assembly can also consist of a mounting base 1, a hinge base 2, a limiting plate 3, and a first pin 4.

[0020] In this embodiment, as a further optimization, please refer to... Figure 2 , Figure 4 and Figure 5The folding support leg includes a second arm 7 and a support leg 9. One end of the second arm 7 is hinged to the top wall of the first arm 5, and the support leg 9 is hinged to the other end of the second arm 7. A first fixing hole 13 and a second fixing hole 14 are provided on the side wall of the second arm 7, and a second pin 15 is provided on the support leg 9. After rotating the support leg 9 to fold it close to the side wall of the second arm 7, the second pin 15 is inserted through the support leg 9 into the second fixing hole 14 to fix the folded support leg 9. When it is necessary to unfold the support leg 9, the second pin 15 is removed from the second fixing hole 14, the support leg 9 is rotated so that the support leg 9 and the second arm 7 are in a straight line, and the second pin 15 is inserted through the support leg 9 into the first fixing hole 13 to fix the unfolded support leg 9. The folding support leg is composed of the second arm 7 and the support leg 9, which allows the folding support leg to be shortened, ensuring that the first arm 5 is not obstructed when rotated to the folding position.

[0021] In this implementation, as a further optimization option, please refer to [link / reference]. Figure 3 The support leg 9 includes a kit 901, a movable leg 903 slidably disposed within the kit 901, a plurality of positioning holes 902 formed on the movable leg 903, and a positioning pin disposed on the kit 901 for insertion into the positioning holes 902; the plurality of positioning holes 902 are arranged sequentially at intervals along the moving direction of the movable leg 903, and the length of the support leg 9 is changed by the movement of the movable leg 903 inside the kit 901, and the positioning pin is inserted into different positioning holes 902 for fixing support legs 9 of different lengths.

[0022] In this implementation, as a further optimization option, please refer to [link / reference]. Figure 2 A support foot 8 is hinged to the end of the support leg 9 away from the second support arm 7.

[0023] Example 2 The following is a detailed explanation using the example of a steering support assembly consisting of a mounting base 1, a hinge base 2, a limiting plate 3, and a first pin 4. Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 The steering support assembly includes a mounting base 1 (such as...) Figure 1The mounting base 1 is T-shaped, with a hinge seat 2 hinged to one side of the mounting base 1 and a limiting plate 3 on the other side of the mounting base 1 (the vertical part of the T-shape of the mounting base 1 is mounted on the vehicle, and the two sides of the horizontal part of the T-shape are provided with hinge seats 2 and limiting plates 3). The limiting plate 3 has two pin holes, and the hinge seat 2 has a insertion hole in which a first pin 4 is inserted. The first support arm 5 is hinged to the hinge seat 2, and the two ends of the driving member 6 are respectively hinged to the first support arm 5 and the hinge seat 2; when the hinge seat 2 and the horizontal part of the mounting base 1 are... When the part is vertical, the insertion hole of the hinge seat 2 coincides with the pin hole of the limiting plate 3 away from the mounting seat 1. The first pin 4 is inserted through the insertion hole into this pin hole to fix the hinge seat 2. At this time, the first arm 5 is in the folded position. The first pin 4 is removed from the pin hole, and the hinge seat 2 is rotated until it coincides with the horizontal part of the mounting seat 1. At this time, the insertion hole coincides with the pin hole of the limiting plate 3 near the mounting seat 1. The first pin 4 is inserted into this pin hole to fix the hinge seat 2. At this time, the first arm 5 is in the working position.

[0024] In this embodiment, as a further optimization, please refer to... Figure 2 , Figure 4 and Figure 5 A first support rod 10 is hinged to the hinge seat 2. A second support rod 11 is hinged to the end of the first support rod 10 away from the hinge seat 2. The end of the second support rod 11 away from the first support rod 10 is hinged to the second support arm 7. A guide groove 12 is provided on the first support arm 5, which extends in the opposite direction along the length of the first support arm 5. The hinge joint between the first support rod 10 and the second support rod 11 is slidably disposed in the guide groove 12. When the driving member 6 extends and drives the first support arm 5 to rotate downward and unfold, the hinge seat 2 does not move. When the first support rod 10 moves away from the hinge seat 2, the end of the first support rod 10 will slide upward along the guide groove 12, applying a pushing force to the second support rod 11, causing the second support rod 11 to push the second support arm 7 away from the first support arm 5, thereby unfolding the second support arm 7 and providing support; when the drive member 6 retracts, driving the first support arm 5 to rotate upward and reset, the end of the first support rod 10 away from the hinge seat 2 will slide downward along the guide groove 12, pulling the second support rod 11 to reset, causing the second support arm 7 to move closer to the first support arm 5.

[0025] Example 3 A mining vehicle includes: a vehicle body and side outriggers mounted on the vehicle body, wherein the side outriggers are folding side outriggers as described above; the mining vehicle can be a ore pass boom conveyor vehicle, and the mounting seat 1 of the folding side outriggers is located on the side wall of the mining vehicle, which can solve the problem of the front frame tilting when the boom is fully extended to deal with ore pass blockage, and can ensure the stability of the frame and make the work safer.

[0026] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
